"My daughter @DaphneOz delivered her first child!" Dr. Oz tweeted the day after Philo's arrival. "I'm holding my beautiful granddaughter now. Thank you for all the well-wishes & prayers!"

"J & I are loving every precious minute with our daughter! happier than we could have dreamed. thank you all for sharing so much sweetness xx," the new mom herself shared last Friday.

Oz announced that she was pregnant during the taping of the ABC show's season premiere back in September.

The reveal began as Oz, along with her fellow Chew cohosts Clinton Kelly, Mario Batali, Carla Hall and Michael Symon, started chatting about their summer vacations. When it was Oz's turn, she spoke about a trip to Italy and France she had taken with her husband. However, instead of showing photographs from her vacation, she pulled out a strip of sonogram images.
